The best type of late night interviews are the ones that go a little bit off the rails.
In The Tonight Show clip above, Honey Don't! star Margaret Qualley randomly challenges Jimmy Fallon to a game of Truth or Dare, which ultimately leads to him conducting part of the interview while lying horizontal on his desk.
It's not quite up there with the famously chaotic Bradley Cooper interview, but it gives Fallon's pillow fight with Dwayne Johnson and "behind the curtain" fight with Martin Short a run for their money.
